How was the division of Korea related to the Cold War?

When the Japanese empire was dismantled at the end of World War Two, Korea fell victim to the Cold War. It was divided into two spheres of influence along the 38th parallel. The Americans controlled south of the line - the Russians installed a communist regime in the north, later ceding influence to China.

The Korean War was one of several military conflicts that occurred during the Cold War, as the United States and its allies attempted to stop the spread of communism. This conflict began on June 25, 1950, when North Korea, a communist nation, invaded South Korea ... After the war, Korea became two countries.
